Like any animal, they have no modesty, so they tend to relive themselves whenever they please. The elephant did just that, and Rob and Reese subsequently got a case of the giggles.

While filming Water For Elephants, the only animal Rob had a problem with was a zebra. During his appearance on BBC One’s The Graham Norton Show, the actor recalled how the animal had charged at the cast – prompting him to move out of its way, forgetting about his co-star Reese Witherspoon.

“Zebras are impossible to tame,” he said. “One of them pulled away and ran towards me and I got out of the way.

He further stated: “Afterwards everyone thought I was a pussy getting out of the way, and apparently Christoph Waltz had got in front of Reese and other actresses and protected them.”
